ROOFING.

Application filed September 8, 1923. Serial No. 661.574.

This inventi n relates to roofing more particularly of somewhat flexible material such as is commonly made of fibroussheet material saturated with waterproofing material, as asphalt. and coated with high melting point asphalt, with or without a surfacing of granular material such as crashed slate. When such material is laid in super posedoverlapping courses any depending tabs or projections exposed to the weather are liable to become raised from the roof as by wind or accidental curling or warping of the material. impairing the appearance of the roof and it pronounced, its \vcatherprooting capabilities also. The tabs or projections are also liable when raised to be torn otl or otherwise damaged. This action is particularly liable to occur when comparatively-large shingle units are being used. as for example, when square shingles are laid diagonally on the roof exposing to the weather all but comparatively narrow portions along their upper converging edges.

According to the present ini'ention, therefore, each shingle is so formed that a portion of its depending corner may be folded backwardly under the adjacent edge of a shingle of an. underlying course.

F or a more complete understanding of this invention, reference may be. had to the accompanying drawings in which Figure 1 is a plan of a shingle formed according to this invention.-

Figure 2 is a fragmentary plan. of aroof showing the shingles of Figure I laid thereon.

Figure 3 is an enlarged detail showing the manner of folding under the edges of adjacent shingle portions cut from the corner of the superposed shingle.

Referring to these drawings, 1 indicates a shingle element of polygonal form, herein shown as square, having the upwardly converging sides 2 and 3 and the downwardly converging sides 4 and 5." The depending corner port-ion as 6 of each unit is cut away to form a pair of tabs 7' and 8, the tab 7 forming a continuation of the marginal portion 5 and the tab 8 being ofi'set. inwardly from the edge 4', but extending parallel thereto. The tube are so formedby a cut; 9 parallel to the edge extending inwardly to the outer edge of the tab 9. a cut 10 parallel thereto defining the inner (dge (it the. tab 4 and the outer end of tab and a cut '11 parallel to the side at den finin; the. inner edge. of the tab 8. The tab respectively, are determined respectively by the lines of out 9 and 11, constituting substantially a continuation thereof and form ing shoulders with the edges of the respeetive tabs 8 and 7. The line of cut 11 also spaces the tab 7 from its inner'eXtre-mity,

being bent backwardly then folded under to enclose the edges 4 and 5 of a pair of slnnglesj of an underlying course adjacent their upper portions. tached to the roof by fasteners suchas nails driven therethrough along the margins ad- .jacent the upper'edges 2 and 3 which will be twerla 'iped by the succeeding course of shingles. hence the margins along the upper edges 2 and 3 are closely tied down to the roof, and as the tabs 7 and 8 of the shin- The shingles are atgles of the succeeding course engage the units of the proceeding: course adjacent these margins, the lower corners of eaclnunit are also held firmly down against the roof. It will be noted that each tab isot less width than the cut away portion shon ingwhen the shin gles are assembled so that the lines of bendin; of the tabs are clearly defined. This construction facilitates bending back of the tabs on the proper lines and avoids danger of touring the material at the apex of the cut out when the bending is effected.

Having thus described an embodimentof this invention it should be evident that varions changes and modifications may be made therein without departing from its spirit said corner, and a tab offset inwardly from the adjacent side edge and subsfimtialiy parallel thereto and extending toward said one marginal, portion.

5 2. A roofing unit having converging side edges having cuts at the apex thereof i 'form a cutaway portion and a tab of less width thansaid cut-sway portion,- said'tzih being folds-hie hack to engage behind the 2.0 edge portion ofan adjacent unit when laid,

one oft-he cuts being'substa'ntiglly parallel to one-6f the said edges oflthe unitand forming a shoulder with an'edge of the tab, thus .dete1'inining the line of fold of said k5 tab.

3.4K unit having converging side wasp edges of the tabs and thus determining she lines of fold of said tabs.

5. A roofing unit having converging side edges having cuts at the apex lhereof to form a cut-sway portion and a lab of less inner extremity.

6; A'roofing unithaving converging side edges haying cuts zit-the apex thereof to form a ciit-awav mrtion and rectan ular ,L..edges-liaving cuts at the apex thereof to tabs adjacent to said cut-away portion-and foldahle bash with their edges substantially parallel respectively to said converging edges of the. unit.

' form: a'wih nmg portion and tabs each of les width than said cutaway port-ion, said i abs being foldable back to engage-behind the edge portisns of adjacent units when laid, certain of said cuts forming shoulders With the edges of each of the labs and thus 'dtem'nining she lines of fold of'said tabs.

25 4. AToofing unit hai'ing' converging side edges iiijiving; cuts at the apex thereof to fond 's out-sway portion, and hills each of 7 less width than said cut-away portion, said tabs being foldahle back to engage behind 89 the edge portions of; adjacent units when i laid, cuts substantially parallel to the side edges of said unit forming-shoulders with 7. A roofing unit. having converging side I edges having'cms at the apex thereof to forn'i a cut-away portion, and rectangular tabs adjacent imsaid cat-away portion and foldnblo hmpk on one of their shorter sides, said labs having their longer sides substantially parallel respectively to said converging sides edges of the unit.

In testimony whereof I have aifixed my signature.
